Question about Dell Inspiron 2200 Notebook

1 Answer

"denial of service": email, firefox, etc. cannot find server..

This computer can reach most sites... but a malicious hacker did something that is preventing connection to only certain site servers.  and use of Firefox to anything.   I've run Registry Mechanic, Symantec, AVG.. and cleaned up a lot.. but this last problem still exists.  It will open Yahoo.com, but trying to log on, presents "This page not available"... same thing on Hotmail.. Absolutely no way to log into email. 

(Can be accessed on another computer..)

Has this been done in the Config?? or where??

    Thanks, Cameron..  At least now I know that was NOT my problem.  Wow, been a LONG time since I used DOS. 
    So what is the problem?  There is Internet Access.. most sites work fine.   It will Not open the sign in page for either of her email addresses , yahoo or hotmail.   I did a ping for both, and they ping just fine.. no loss. 
    It also will not allow Firefox to operate at all. ???  only IE.  Thanks again for your help.

  • Tutor281 Oct 19, 2007

    Thanks For the offer, Cameron.  I think I;ve found where a part of the problem is.. a bad installation of Symantec Internet Security 2004 which won't let me remove it.  No authorization and can't get it!
    There's also a problem with scripts.
    I would gladly have you fix it, but don't you need XP pro on the machine to fix it remotely?  She has XP home. 
    I think we're going to need a Hard Drive reformat, but I don't know if she has a disc for the OS.

  • Tutor281 Oct 19, 2007

    Did my comment about the scripts post??

  • Tutor281 Oct 19, 2007

    Thanks, Cameron..  The scripts problem is only with Internet Explorer.. SO.. we can well do without THAT!.  Using Firefox has no problems.. Symantec is gone, so no problem there.  
    All is working FINE.. Thanks so much.  What do I owe?

What told this was a "denial of service"?

Some hackers use DoS (above) it's considered the worst thing you can download, they can go from keylogging your PC, from taking over your pc anytime they like, and using your bandwidth which is called DDOS.

This is a very compllicated thing to get ride of,

One way you can test to see if your a victum of this is to check the port, here is how:

To open the MS Dos screen go to:
Start>Run>type "cmd" and press enter (without quotes)


All of the IRC Zombie/Bots open and maintain static connections to remote IRC chat servers whenever the host PC is connected to the Internet. Although it is possible for an IRC chat server to be configured to run on a port other than "6667", every instance I have seen has used the IRC default port of "6667".

Consequently, an active connection to an IRC server can be detected with the following command:

netstat -an | find ":6667"

Open an MS-DOS Prompt window and type the command line above, then press the "Enter" key. If a line resembling the one shown below is NOT displayed, your computer does not have an open connection to an IRC server running on the standard IRC port. If, however, you see something like this:

TCP 192.168.1.101:1026 70.13.215.89:6667 ESTABLISHED

. . . then the only question remaining is how quickly you can disconnect your PC from the Internet!

A second and equally useful test can also be performed. Since IRC servers generally require the presence of an "Ident" server on the client machine, IRC clients almost always include a local "Ident server" to keep the remote IRC server happy. Every one of the Zombie/Bots I have examined does this. Therefore, the detection of an Ident server running in your machine would be another good cause for alarm. To quickly check for an Ident server, type the following command at an MS-DOS Prompt:

netstat -an | find ":113 "

As before, a blank line indicates that there is no Ident server running on the default Ident port of "113". (Note the "space" after the 113 and before the closing double-quote.) If, however, you see something like this:

TCP 0.0.0.0:113 0.0.0.0:0 LISTENING

. . . then it's probably time to pull the plug on your cable-modem!

Note that a Windows IRC client program running in the PC will generate false-positive reports since these are tests for IRC client programs. So be sure to completely exit from any known IRC client programs BEFORE performing the tests above.

    Oh sorry.

    What happens when she tried to open programs? Does it just ask you what to open it with?

    If so she may need ".net framework"
    http://www.microsoft.com/downloads/detai...

    Theres a new one out 3.0 but this should do it.

    Can she open and install any other programs?
    -If she can go here www.grisoft.com get a trial of the anti-malware and run a scan and delete all threats.


    Thanks,
    Cam

    Also my friend Hady, he had tat problem where FF wouldn't work, only IE. So I told him to download the grisoft what I just gave you, it found a Trojan and he deleted it. And now his FF works, that might be the same with you.

    Good luck,

When I go to the website straight talk to inquire about my phone service my antivirus said it was a malicious site and I want to know why


Two possible reasons
The web site is on some sort of database with the antivirus and the IP address is being flagged as malicious. The web server that the web site is on may have another web site on it that is malicious and the anti virus has rejected the web server ip address.

Reason 2. The web site contains malicious Java script code or tracking cookies that are malicious in nature.

Another situation
The site is using encryption SSL the URL would start with HTTPS and the security certificate is outdated or incorrect. Would come up as certificate problem .

You attempted to reach www.facebook.com, but instead you actually reached a server identifying itself as *.vkontakte.ru. This may be caused by a misconfiguration on the server or by something more serious....


Usually this is because you have downloaded a malicious file which has changed your hosts file and is redirecting facebook.com to vkontakte.ru

In order to change this, follow these steps:

1- Go to Start->Run
2- Type C:\Windows\system32\drivers\etc\ (unless you have a different Windows directory, use that instead of C:\)
3- Open the file hosts with notepad
4- Remove everything, and type:

127.0.0.1 localhost

5- Save changes and restart you computer.

Have fun :)

Gmail got hacked. I wa able to get it back, but the hackers deleted all my inbox gmails and emails in folders /Lables. I followed all the online info and still can not recover old inbox emails. help, what...


Hi and welcome to FixYa!

Unless they didn't empty out your trash folder,

you have another email server that the mail goes to something like incredimail, outlook, etc.

Or it went to spam, those will not be able to be recovered.

You should make sure to look in your settings though if you were hacked. Many times,

hackers put in their own email as an alternate email and when you change passwords, security

questions etc, they will now get all of your mail also!

Change everything and look to see if there is an alternate email attached to your account that you

don't recognize. Sorry for the bad news.

Someone sent spam email purportedly from me to everyone on my contact list. How can I prevent this from happening again?


Perform an immediate virus scan, your computer may be infected. Hackers get in through malicious links you may have clicked, and this is what results from those hacks.

Also perform malware and spyware scans, either of these can cause an issue such as this as well.

Change your password frequently, make it difficult so a hacker cannot gain access to your account.

Be sure to change your password after performing these scans, otherwise anything on your computer that a hacker will have, they will still have if you change your password prior to the scan.

Problem signing in to yahoo account


try to check if your internet connection is working properly. download the latest version of mozilla firefox. And try to use it.
If you keep experiencing problems when your internet connection is ok, then try to scan your computer for malwares that try to block the site.,

usually this happens on ( DOS ) Denial of Service and the thing that may cause these are viruses,spywares, malwares and worm.

Pm me if the problem continues.
i will provide another solution..
Thank you.. :)

Hacker - computer issues


Snail mail? Well good! You have documentation, that will lead right back to this hacker! I'll bet it's a friend playing a joke.

BUT, have you heard of the FBI? Really! They may be interested in your letter. Your local law enforcement probably won't be. City police, county sheriff department, highway patrol, state trooper.

The reason the FBI may be interested, is that this may be a small lead for them. Help them to narrow down a search, for someone/s they're looking for.
How about letting them see if it's worth the time.
This may be part of a large scale cyber crime ring.

Probably better find out if it's a friend, or cyber buddy first. The FBI doesn't play!
